Effect of a subcutaneous administration of exendin-4 (100 nmol/kg, s.c.) on cardiovascular functions, core body temperature and gastric myoelectric activity. (A) Mean arterial BP, (B) heart rate, (C) heart rate variability, (D) core body temperature, (E) dominant frequency, power repartition in the (F) bradygastric, (G) normogastric and (H) tachygastric ranges are shown. 1. Injection of saline or exendin-4, 2. Food was presented to both groups. BP = blood pressure, HR = heart rate, HRV = heart rate variability, Sal = saline, Ex-4 = exendin-4. Data represents the mean ± s.e.m. of 8 animals. Significant differences are shown as **P < 0.01 (repeated measures two-way ANOVA followed by Bonferroni tests).
